Abstract

The present disclosure provides embodiments directed towards a system for the control of hydraulic output by a hydraulic power source. In one embodiment, a system is provided. The system includes a hydraulic supply system having a drive, a hydraulic pump (304) coupled to the drive, a first hydraulic output configured to supply a first flow of a hydraulic fluid from the hydraulic pump (1) to a hydraulic lift (324), a second hydraulic output configured to supply a second flow of the hydraulic fluid from the hydraulic pump (2) to a first hydraulic tool (320). (1) through a first valve (326) (2) through a second valve (312).
